Background: Rarely, cardiac pacemaker implant can lead to the development of involuntary hyperkinetic movement disorders localized to the abdominal wall or the diaphragm.

Phenomenology Shown: We report a case of a 79-year-old female who developed rhythmic continuous clonic right abdominal movements caused by cardiac pacemaker lead dislodgement.

Educational Value: Our case highlights that, in the differential diagnosis of hyperkinetic abdominal movement disorder, the presence and the possible pathogenic role of a cardiac pacemaker should be kept in mind.
